Abstract

The piecewise-constant vorticity method of Tuck* for solution of the lift- ing surface integral equation determines accurately integrated quantities such as the lift produced by planar lifting surfaces. Here a modification to this method is presented whereby the leading-edge singularity strength and leading-edge suction force, and hence the induced drag, may also be calculated accurately. Introduction Lifting surfaces may be wings on airplanes or birds, windmills, racing car downforce devices, aerodynamic aids such as tails or fins on airplanes or dragsters, frisbees or aerobees, paper planes, kites, control surfaces in air or water, hydrofoils, boomerangs or re-entry space vehicles. In all cases, forward motion induces a pressure difference be
